FMWrapper Framework

The FMWrapper Framework is the C/C++ API supplied by FileMaker, Inc. to which you create and compile FileMaker plug-ins against. It is included with FileMaker Pro Advanced and cannot be redistributed in any form. The framework you compile plug-ins against is a stub framework consisting of 10 header files that make up the API.
